BENDING BEAM ANALYSIS FOR REINFORCED CRUMB RUBBER CONCRETE BASED ON STRAIN ENERGY
-
摘要: 依据橡胶集料混凝土本身固有的特色,其压应力-压应变曲线下面积,即应变能,比普通混凝土应变能大的特征,初步探讨了橡胶集料钢筋混凝土梁正截面受弯的基本性能,并与C50及以下强度等级的普通混凝土进行了比较,发现橡胶集料钢筋混凝土梁正截面最大受弯承载力与其内部应变能的变化有密切关系。由此建议,尝试用应变能作为钢筋混凝土梁设计参数。Abstract: In comparison to controlled concrete, crumb rubber concrete (CRC)exhibits a higher value of strain energy.It is presented a bending analysis of a reinforced beam made with CRC as well as controlled concrete of C-50 and under.It is found that the maximum loading capacity of CRC beam can be expressed by the variable of strain energy in place of the quantity of 28 day maximum concrete compressive strength, which may be used in the current beam design.
